Carriage clock

A carriage clock, approximately 10cm tall

A carriage clock is a small, spring-driven clock, designed for travelling, developed in the early 19th century in France, where they were also known as "Officers' Clocks". The first carriage clock was invented by Louis Breguet for the Emperor Napoleon in 1812. The case, usually plain or gilt-brass, is rectangular with a carrying handle and often set with glass or more rarely enamel or porcelain panels. A feature of carriage clocks is the platform escapement, sometimes visible through a glazed aperture on the top of the case.
